Abstract
This paper examines pragmatic failure in the use of English numerical idiomatic expressions among Uzbek EFL learners. Figurative and culture-bound meanings of idioms often cause misunderstandings and inappropriate usage in intercultural contexts. Using principles of pragmatics and cognitive linguistics, the study analyzes instances of pragmatic failure based on data from a Google Form questionnaire completed by 140 students at Urgench State University. The research emphasizes how the Uzbek linguistic worldview influences idiomatic interpretation, affecting learners' comprehension and application of idioms in English. The findings indicate that Uzbek EFL learners' pragmatic competence in understanding numerical idioms is generally satisfactory; however, they experience pragmatic failure with some idioms involving numbers. This failure results from literal interpretation or transferring native cultural metaphors. The study aligns with previous research, emphasizing that pragmatic competence is not solely linguistic but also rooted in cultural cognition. Such competence can be improved through understanding cultural norms or living within the society. Limitations include focusing only on idioms with numbers and participants from a single educational context, which may not fully represent all Uzbek learners.
